Answer:

\frac{(x)^{2}}{49}+\frac{(y)^{2}}{1}=1

Step-by-step explanation:

In this problem we have a horizontal ellipse, because the major axis is the x-axis

The equation of a horizontal ellipse is equal to

\frac{(x-h)^{2}}{a^{2}}+\frac{(y-k)^{2}}{b^{2}} =1

where

(h,k) is the center of the ellipse

a and b  are the respective vertices distances from center

we have

vertices at (7, 0) and (-7, 0)

co-vertices at (0, 1) and (0, -1)

so

The center is the origin (0.0) (The center is the midpoint of the vertices)

a=7

b=1

substitute

\frac{(x-0)^{2}}{7^{2}}+\frac{(y-0)^{2}}{1^{2}}=1

\frac{(x)^{2}}{49}+\frac{(y)^{2}}{1}=1

80 POINTS HELP<br> 1. What is the value of x? Show all of your work.
AnnyKZ [126]

Answer:

x = 9cm

Step-by-step explanation:

This is a right triangle so we can use the Pythagorean theorem

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

6^2 + x^2 = ( sqrt(117) ^2)

36 + x^2 = 117

Subtract 36 from each side

x^2 = 117 -36

x^2 = 81

Take the square root of each side

sqrt(x^2) = sqrt(81)

x = 9

In converting 540 inches into yards what unit would you place in the numerator of your ratio?
Lesechka [4]

Answer:

The change division should put the unit to be dispensed with as an afterthought inverse of where it happens in the first inquiry.

540 inches * (1 yard/36 inches)

The inches best and base drop, abandoning you with the outcome in yards.
